3.2.2
Receiver side
Receiver side consists of steganography and cryptography stages. In receiver side we
will first extract embedded data then decrypt it.
Steganography Stage :
In the receiver side, we start with steganography then cryptography. We will use the
same steps which are used in sender side.
Input= Stego-Image+ Secret Key.
Output= Encrypted Message.
Cryptography Stage :
In cryptography stage, we use the data which is extracted from stego file and use RSA.
We will use the same steps which are used in sender side. The Decryption can be done
using the Encrypted message, receivers private key and senders public key.
Input= Encrypted Message + 2 Prime Numbers.
Output= Plain Text.
Now the Plain Text is in the form of Base-64. After getting the plain text apply Base-
64 coversion to change the Plain-text to given input, which can be Text, Image,
Video, Audio.
